We had time for lunch and shopping in the historic district before boarding the ship for the harbor cruise. We decided to eat at DiMillo’s, the only floating restaurant on the east coast. The boat is a converted car ferry that was purchased by the DiMillo family in 1980. A few years prior to this Mr DiMillo purchased the dilapidated Long Wharf and soon converted it into boat slips. There are now 120 slips at this wharf in the main part of historic Portland. We ordered a large salad and a grilled haddock sandwich. It was quite delicious. We had never eaten haddock and really like it. After lunch we walked through Exchange Street in the historic area where business dealings took place years ago. It is now filled with shops of all kinds.
